through the body is called electrical impedance. Hence, by measuring the electrical impedance and
applying to the data a proprietary algorithm, %BF can be estimated.
‘Please note that the percentage of body fat and body water will not add up to 100%.’
Please be reminded that the %BF estimated with the scale represents only a good approximation of
your actual body fat. There exist clinical methods of estimating body fat that can be ordered by your
physician.
3. Why is it important to monitor percentage Total Body Water (%TBW) in the body?
Water is an essential component of the body and its level is one of the health indicators. Water makes
up approximately between 50-70% of the body’s weight. It is present proportionally more in lean tissue
compared to fat tissue. Water is a medium for biochemical reactions that regulate body functions.
Waste products are carried in water from cells for excretion in urine and sweat. Water provides form to
cells; helps to maintain body temperature; provides moisture to skin and mucosa; cushions vital organs;
lubricates joints and is a component of many body fluids. The amount of water in the body fluctuates
with the hydration level of the body and state of health. Monitoring the level of body water can be a
useful tool for one’s health maintenance. Similar to body fat estimation, the %TBW function provided in
this scale is based on BIA. The estimated %TBW may vary according to your hydration level, that is, how
much water you have drunk or how much you have sweated immediately prior to the estimation. For
better accuracy, avoid fluctuation in hydration level prior to the estimation. The accuracy of the scale in
estimating TBW will also decrease with individuals suffering from diseases that tend to accumulate
water in the body.
Please be reminded that the %TBW estimated with the scale represents only a good approximation of
your TBW. There exist clinical methods of estimating total body water that can be ordered by your
physician.
The optimal %BF and TBW% of an individual varies according to age and gender.
